I have an Asus EAH3850 card with an annoying problem. If you boot the comp with an lcd attached to the dvi port, it wont show video until windows boots. If i hook up a crt(vga analog) it will show post text and all. Is the card defective? I put in a spare 4650 that i had lying around and it worked fine with dvi hooked up. Is there something that i can do to fix this or is the card done?
